Extinguishing agent HFC 227

The extinguishing agent HFC 227 ea is a colourless, odourless gas which does not conduct electricity and has a density that is approximately six times greater than that of air. It is an extinguishing agent with low toxicity as far as gases go, and it therefore provides sufficient security because it does not cause serious harm to persons even if they are exposed to it for relatively long periods of time. In fact, the manufacturers assure you that the permitted exposure time is two minutes with a concentration of 10%. Its chemical-physical characteristics make it very practical in many cases where it is necessary to protect environments which have delicate materials inside: in fact, it doesn’t leave any dirt or residue, and it is not corrosive.

HFC 227 ea total saturation systems can be used to extinguish fires of all classes.

The cylinders are equipped with a rapid-flow valve which, when activated by a control, allow a rapid and safe discharge of the extinguishing agent.

The valves are fitted with a pressure gauge for the visual control of the cylinder pressure and with a minimum pressure switch which, when connected to the alarm centre, sends out a signal if the pressure inside the cylinder drops below the calibrated threshold.

The discharge nozzles are made of chromium brass with a threaded joint, and they are calibrated to ensure the correct discharge of the gas which lasts between 10 and 20 seconds.
